The decapod crustaceans of the families Tetraliidae and Trapeziidae from the Early Eocene (middle-late Ypresian) of Monte Magrè (Schio, Vicenza, NE Italy), are described. The specimens are assigned to Eurotetralia loerenthey (Müller, 1975) n. gen., Tetralia vicetina n. sp. (Tetraliidae Castro, Ng & Ahyong, 2004); Archaeotetra lessinea n. sp., Eomaldivia trispinosa Müller & Collins, 1991, Paratetralia convexa Beschin, Busulini, De Angeli & Tessier, 2007, and Paratetralia sulcata n. sp. (Trapeziidae Miers, 1886). The specimens were discovered associated with other decapods, in the coral-rich limestone. This report is the oldest fossil record of both two families. The stratigraphical distribution of the Tetraliidae and Trapeziidae is extended back to the middle-late Ypresian.
